Application filed January 25, 1924; Serial No. 688,488.

This invention relates to scouring wheels and more particularly'todevices'for buffing or scouring the breast portion of the heel of a bootor shoe.

The invention is herein ill'ustratedas embodied in buffing or scouringdevicev of the type shown in United States Letters Patent No. 1,048,957,granted December 31, 1912 on application of 'C. E. Graham. In the devicedisposed, in conical form is supported by a conical portion ofcompressed felt, and the base of the cone is supported in turn bymetallic and non-metallic disks, these parts being all mounted upon asupporting sleeve. While scouring devices of this type have been usedextensively and successfully, some of the devices have been found todevelop relative rotation of the various disks upon the supportingsleeve with resulting distortion and injury to or destruction of theabrasive covering.

lVith this in view, an object of this invention is to provide animproved scouring wheel of this type constructed and arranged so aspositively to prevent the relative rotation of the component parts. Thisis accomplished in the illustrated construction in accordance with'thepresent invention by in terlocking the disks with one, another and oneof the disks with the supporting sleeve.

A preferredform of the invention is illustrated in the accompanyingdrawing and will be described in the following specification, but itwill be understood that the scope of the invention is not limited to theexact showing and should be determined by reference to the accompanyingclaim when construed by reference to the prior art.

somewhat larger raised seat portion 16 and is provided with an annularflange 18, as

rotation of the parts.

A) shown in this patent, an abrasive covering.

In the drawing, Fig. 1 is a side elevation in the device of the patentto which reference has been made above. In assembling the device, aslight cupped steel disk 20 is forced on to theraiscd portion 16 of thesleeve 1 9 with a driving tit and in many cases this is found sufficientto prevent relative A similarly cupped disk of leather or leatheroid 22is next applied and may be glued to the inner face of the steel disk 20,if desired. It is noted that a reversed relation of the disks is foundin said Letters Patent. A foundation p0rtion 24: of compressed felt,substantially conical in shape, is next forced onto the sleeve 10 and isglued to the outersurface of said sleeve and to the inner face of theleather disk 22. In order to assist in holding the felt portion upon thesleeve, grooves 26 are provided into which the felt expands itself andto which it is attached by the glue previously applied. An abrasivecovering 28 is then applied to the outer surface of the assembled partsand is held in position thereon by means of a knurled sleeve 30, whichis screw threaded at 32 to the inner end of the supporting sleeve 10. Itwill be observed that the outer surface of the leather disk 22 forms anextension of the conical surface of the felt portion 24 and serves as anon-metallic, somewhat resilient peripheral support for the abrasivecovering thereby to avoid'damage in case it accidentally contacts withthe shank of the shoe.

Exceptas above noted the construction thus far described issubstantially like that shown in the said Letters Patent, and in spiteof the precautions taken to prevent displacement of the parts,suchdisplacement has occurred with sufficient frequency so that itbecomes desirable positively to interlock the metallic disk 20, theleather disk 22 and the sleeve 10. To thisend I have provided asubstantially rectangular recess 34 in the inner periphery of theleather disk 22 and have struck up a coinplementally shaped tongue 36from the steel disk 20 exactly in position to enter the recess 34.Preferably this tongue will have parallel sides coacting with the sidesof the recess. The entrance of this tongue 36 in the recess 3 L securelyI interlocks the leather and the steel disks against relative rotation.

As an additional safeguard, I have further provided an arran ement forinter locking thesteel disk and hence the leather disk With the flangeof the supporting sleeve 10. To this end a complementally shaped tongueor spur 38 has been struck up from the annular flange 18 of the sleeveand positioned to enter the recess provided by the bending up of thetongue 36 thereby positively to prevent relative rotation of the steeldisk 20 upon the supporting sleeve. Preferably the spur 38, Will haveparallel sides coacting with the sides of the recess in the steel diskand Will be substantially the same Width as the tongue 36.

It will be apparent to those skilled in the art that the tongue and thespur, as above described, preferably Will be struck up before the partshave been assembled, but such a method of construction and the exactdesign of the tongue and spur, as illustrated herein, are not absolutelyessential to the successful operation of the invention.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent of the United States is A heel breast scouringWheel having, in

combination, a supporting sleeve provided- With a flange at one" end, ametallic disk arranged on said sleeve in proximity to the flange, anon-metallic disk extending beyond the periphery of the metallic diskand arranged on the sleeve in proximity to the metallic disk, resilientconical means arranged to cooperate With the edge of the nonmetallicdisk in supporting an abrasive covering, said means surrounding saidsleeve and abutting said non-metallic disk at the base of the cone, saidnon-metallic disk being provided With a recess adjacent to thesupporting sleeve, and means positively to prevent the relative rotationof the nonmetallic disk and the supporting sleeve comprising a tonguestruck up from the metallic disk to enter the recess in the non-metallicdisk, and a spur struck up from said flange on the supporting sleeve toenter the recess formed by the bending of the afore-mentioned tongue. I

In testimony whereof I have signed my name to this specification.
